Polarized Raman Spectroscopy

Dear friends
I have a question regarding to polarized Raman spectroscopy. When we are talking about parallel and perpendicular electric field of the laser, is the magic angle 90° or 54.7°?
I'd be grateful if you could answer me as soon as possible.
Best wishes

oh actually it has
when you linearly polarise the light, you are rotating and adjusting its electric field to a specific angle
This is the base of techniques such as linear dichroism, circular dicroism, polarised Raman spectroscopy and polarised IR spectroscopy.
